An open-source solution that provide good detection and more visibility

The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.

Has cloud-first architecture with SIEM technology to run security operations

When it comes to scale, they're architected quite well. They handle some of the biggest customers globally, with significant throughput on their platform, managing thousands of customers. One of the most impressive aspects of Devo is its customer community. A large majority, over 80 percent of their customers, actively participate on a Devo-specific community page. They're contributing to product development and support, events, and user group information, helping each other out. This high level of engagement is rare and demonstrates both the loyalty of their customer base and the quality of their product. They offer a range of small, medium, and large options to cater to everyone. I sold Devo products while working with them, focusing on enterprise solutions. However, as a small reseller, my customers were typically smaller businesses. I rate the solution's scalability a nine out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."

"Network traffic analysis is highly efficient."

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."

"Better than other SIEM solutions because almost everything can be integrated."

"The solution is very stable. Compared to Qradar and Splunk, it's very stable."

"With AlienVault you get everything in one box."

"The paid version of the solution has reporting and better scalability options."

"The dashboard is the solution's most valuable aspect. It brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on.""

More AlienVault OSSIM pros

"The ability to have high performance, high-speed search capability is incredibly important for us. When it comes to doing security analysis, you don't want to be doing is sitting around waiting to get data back while an attacker is sitting on a network, actively attacking it. You need to be able to answer questions quickly. If I see an indicator of attack, I need to be able to rapidly pivot and find data, then analyze it and find more data to answer more questions. You need to be able to do that quickly. If I'm sitting around just waiting to get my first response, then it ends up moving too slow to keep up with the attacker. Devo's speed and performance allows us to query in real-time and keep up with what is actually happening on the network, then respond effectively to events."

"The most valuable feature is definitely the ability that Devo has to ingest data. From the previous SIEM that I came from and helped my company administer, it really was the type of system where data was parsed on ingest. This meant that if you didn't build the parser efficiently or correctly, sometimes that would bring the system to its knees. You'd have a backlog of processing the logs as it was ingesting them."

"The alerting is much better than I anticipated. We don't get as many alerts as I thought we would, but that nobody's fault, it's just the way it is."

"In traditional BI solutions, you need to wait a lot of time to have the ability to create visualizations with the data and to do searches. With this kind of platform, you have that information in real-time."

"The user experience [is] well thought out and the workflows are logical. The dashboards are intuitive and highly customizable."

"Scalability is one of Devo's strengths."

"The most useful feature for us, because of some of the issues we had previously, was the simplicity of log integrations. It's much easier with this platform to integrate log sources that might not have standard logging and things like that."

"Devo helps us to unlock the full power of our data because they have more than 450 parsers, which means that we can ingest pretty much any type of log data."

More Devo pros

Cons

"The user interface could be improved."

"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."

"AlienVault OSSIM should improve the deployment and make it unified like the USM."

"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."

"They can add more compliance templates."

"The solution needs more integration with cyber intelligence systems."

"The incidence reporting could be better."

"The price of this solution is very high and it could be cheaper."

More AlienVault OSSIM cons

"The biggest area with room for improvement in Devo is the Security Operations module that just isn't there yet. That goes back to building out how they're going to do content and larger correlation and aggregation of data across multiple things, as well as natively ingesting CTI to create rule sets."

"I would like to have the ability to create more complex dashboards."

"Where Devo has room for improvement is the data ingestion and parsing. We tend to have to work with the Devo support team to bring on and ingest new sources of data."

"There's always room to reduce the learning curve over how to deal with events and machine data. They could make the machine data simpler."

"Some basic reporting mechanisms have room for improvement. Customers can do analysis by building Activeboards, Devo’s name for interactive dashboards. This capability is quite nice, but it is not a reporting engine. Devo does provide mechanisms to allow third-party tools to query data via their API, which is great. However, a lot of folks like or want a reporting engine, per se, and Devo simply doesn't have that. This may or may not be by design."

"Devo has a lot of cloud connectors, but they need to do a little bit of work there. They've got good integrations with the public cloud, but there are a lot of cloud SaaS systems that they still need to work with on integrations, such as Salesforce and other SaaS providers where we need to get access logs."

"We only use the core functionality and one of the reasons for this is that their security operation center needs improvement."

"There's room for improvement within the GUI. There is also some room for improvement within the native parsers they support. But I can say that about pretty much any solution in this space."

More Devo cons

Pricing and Cost Advice

"OSSIM is free."

"AlienVault OSSIM is an open-source solution."

"OSSIM is open source, and USM is the paid license. So, if you want, you can switch to USM. There you will have to buy a license, and they have a support team that helps you out on issues you face."

"The price of AlienVault OSSIM is too high sometimes for us to present to our customers. The price should be lower. We are on a three-year license to use the solution. We had to pay extra for the support."

"AlienVault pricing is the best. Whatever cost you are paying, you are getting a return on every penny... It's not like your IBM, your QRadar, or Splunk, where the cost is too high."

"The solution is open source, so it's free to use."

"AlienVault OSSIM is expensive compared to its competitors."

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."

More AlienVault OSSIM pricing and cost advice

"Devo is definitely cheaper than Splunk. There's no doubt about that. The value from Devo is good. It's definitely more valuable to me than QRadar or LogRhythm or any of the old, traditional SIEMs."

"I rate the pricing a four on a scale of one to ten, where one is cheap, and ten is expensive."

"[Devo was] in the ballpark with at least a couple of the other front-runners that we were looking at. Devo is a good value and, given the quality of the product, I would expect to pay more."

"Devo is a hosted or subscription-based solution, whereas before, we purchased QRadar, so we owned it and just had to pay a maintenance fee. We've encountered this with some other products, too, where we went over to subscription-based. Our thought process is that with subscription based, the provider hosts and maintains the tool, and it's offsite. That comes with some additional fees, but we were able to convince our upper management it was worth the price. We used to pay under 10k a year for maintenance, and now we're paying ten times that. It was a relatively tough sell to our management, but I wonder if we have a choice anymore; this is where the market is."

"Be cautious of metadata inclusion for log types in pricing, as there are some "gotchas" with that."

"Devo was very cost-competitive... Devo did come with that 400 days of hot data, and that was not the case with other products."

"Pricing is based on the number of gigabytes of ingestion by volume, and it's on a 30-day average. If you go over one day, that's not a big deal as long as the average is what you expected it to be."

"It's very competitive. That was also a primary draw for us. Some of the licensing models with solutions like Splunk and Sentinel were attractive upfront, but there were so many micro-charges and services we would've had to add on to make them what we wanted. We had to include things like SOAR and extended capabilities, whereas all those capabilities are completely included with the Devo platform. I haven't seen any additional fee."
